Colorful copper compounds I've made so far
Hello all
I've been playing around with making various copper compounds and have photographed a few so far.
In the photos below I have copper (II) acetate, copper (II) Fluoride, Copper Cyanurate and an amethyst colored copper cyanurate ammonia complex. Does
know of any other really neat copper compounds to make. I have also made CuCl2, CuCl, CuI, CuBr2, copper carbonate, hydroxide, and the oxide, I'm
thinking about trying to make the trifluoroacetate salt also.
I'm also looking at making potassium Hexafluorocuprate.

and how exactly did you make the copper fluoride, HF + copper carbonate?

Yep! I kept adding HF untill the Fizzing stopped and the color of the precipitate changed. I also made this in a plastic container.
I have read that Copper (II) Fluoride can react with potassium fluoride to form Potassium Hexafluorocuprate. Which I shall be trying to make sometime
soon now.

Perhaps the simplest to make and best saturated blue copper
chemical is "tetraamminecopper sulphate". Just add ammonia
water to copper sulphate. However, I have never tried to dry it.
Something in the back of my mind says - add a little alcohol.
I don't have time to try it now.

You can buy 3% HF as Whink Rust remover. It comes in a brown bottle and can be found at most supermarkets as well as hardware stores in the US. It is
pretty safe. But I would still use it in a ventilated area with rubber gloves and goggles. Nothing is worse then an HF burn to the skin, eyes, or
lungs. Fluorides also cause fluorosis of the bones. The copper salt is quite safe due to it's insolubility in water.

Ah yes copper Tetraamine sulfate. It can be crystalized from solutiont to form dark purple orthorhombic crystals if the solution is allowed to
evaporate. I have found that the crystals are heat sensitive and decompose on strong heating to copper (II) Oxide.

Just a note:
I made the Copper Cyanurate/ ammonia complex by reacting copper carbonate with ammonia to form the tetraamine complex; then powdered cyanuric acid was
added. The complex can also be made from Copper Tetraamine sulfate and cyanuric acid but it doesn't seem to work as well.

I made some copper II bromide which is black and upon heating it vaporizes to form a gas.

Here is some Copper Phosphate, made by mixing correct molar proportions ofCuSO4.5H2O and Na3PO4. It forms a very pretty turquoise precipitate, but
doesn't settle out. I let the jar sit for a few days and siphoned off the supernatant , and added fresh distilled water and mixed. I repeated this
over 4 times. The final mass is very light, and was allowed to air dry slowly by covering the plastic jar mouth with a paper towel and a rubber band.
The material was to prepare an artificial turquoise when mixed with AlPO4, but other projects took over. What would be the best way to make a soluble
Aluminum salt from household materials. I don't have access to Alum, which would be convenient.

I have some TSP I might have to try making Copper (II) Phosphate.
Aluminum will react with HCl H2SO4, Sodium aluminate can be made by reacting NaOH solution and aluminum metal too!

very nice i have no Na3PO4 =(
but you can add aluminium foil to HCl and then filter to make a solution of aluminum chloride

Nice. Have you checked out Woelen's website? He has done some fun things with Cu!

saw this on ozone's site seemed interesting might give it a try
Dicopper (II) Acetyloxybenzoate synthesis
16, 300mg Aspirin tablets are crushed.
The resultant powder is dissolved in 100ml of a 1M Potassium Carbonate solution to dissolve the Acetylsalicylic Acid.
The insoluble binders are then removed via vacuum filtration.
The remaining solution is then acidified to pH1 with 10% Hydrochloric Acid to precipitate out the Acetylsalicylic Acid from solution.
This foamy solution is then vacuum filtered and washed with more dilute Hydrochloric Acid to obtain a more pure product.
This is then re-dissolved in the minimum amount possible of Potassium Carbonate solution, just so much that there are no unreacted reactants.
This solution is then combined with a previously prepared 0.01M solution of Copper Sulphate with stirring.
Bright blue crystals of Dicopper (II) Acetyloxybenzoate precipitate immediately.
These crystals are vacuum filtered. This is an extremely slow process.

Did you make copper(I) oxide as well as copper(II) oxide?
There are also two different forms of copper(I) oxide, a red one and a yellow one.

fairly easy
copper sulfate + nahco3 solution
then dry the copper carbonate and heat till it decomposes to CuO
